ELECTRICAL APPARATUS FOR SEPARATINGCOKE FROM CINDERS, ac.

SPECIFICATION forming part of Letters Patent No. 781,437, dated January31, 1905.

' I v Applicationfiled April 13, 1904. Serial No. 202,957.

To aZZ whom, it may concern Be it known that I, HENRI LELARGE, of 808Rue de' Renory, Kinkempois, Liege, Belgium, have invented a new anduseful Improved Electrical Apparatus for' Separating'Coke from Cindersand other Substances, of which the following is a full, clear, and exactdescription.

This invention relates to the separation of coke from cinders and. othersubstances such as stones, slate, and the likefrequently embodied incoal. I

The object of'the invention'is to provide mechanism which Will quicklyand efliciently effect the separation by means of electricity.

and deposit the assorted coke and other substances into respectivereceptacles.

For a detailed description of my invention 1 reference is to be had tothe accompanying drawings, wherein- Y Figure is a side'e levation,partly in section, of my improved apparatus. Fig. 2 is a planillustrating parts of the mechanism shown in Fig. 3 is a detail viewillustrating parts shown in Figs. 1 and 2 drawn to a larger scale. anismdrawn to a larger scale.

A refers to a rotary sifter which assorts the cinders, &c., and depositsthem upon the in-' clined plate B, from whence they fall onto they Iinclined plate 0.

A drum D is rotatably carried by a'suitably-supported shaft Xand hassecured toits ends ratchet or toothed wheels E. On the circumferentialsurface of the drumare radially and longitudinally arranged angle-ironsF. The longitudinal channels formed by the irons F are transverselydivided by a series of plates H, which are suitably supported by afixture, as A, and the end ones extend downwardly below the drum. i

Pivotally mounted on the shaft X are two rockinglevers J, to which anoscillatory movement is'ir'nparted by wrist-pins U of crankdisks U onshafts X. The levers-J each carry a depending link I, connected to oneend of a pivoted rock-bar I, to the other end of I which is pivoted thepawl I, which engages the teeth of the wheel E.

Fig. 4: illustrates the electrical mech-- depending rods Q, which areadjustably connected, by means ofa pivot Q and slot in the bar-rod, tothe frame which carries 'electro magnets S. This frame is pivoted on asuitably-supported shaft Y and carries the arms S. .The shaftY hashinged to it, an armature T with the battery P, and the battery isconnected by a wire T to any suitableparts of the drum D. I I

The operation of the apparatus is as follows: (Joke, cinders, &c., fall,as before mentioned,

from the sifter A to the chutes B and O and enter the spaces between theangle-irons F and are retained in even distribution along said spacesbythe plates H. By the rotation of the drum D the coke, cinders, &c.,are carried around until they are brought into contact withthe metallictongues K. During the rotation of the drum D, which receivesanintermitt'ent motion from the pawls I and wheels E, the electromagnetsare rockedabout the shaft Y by the rods Q and levers J. vWhen cindersand other matter which are not contact with the tonguesK, they simplypass to the chute G and fall into asuitable receptacle. VVhen', however,coke or other conductors of electricity are-brought into contact withone of the tongues K, an electrocircuit is made through the drum D, wireT, battery P, wire T,.-electromagnets S, and wire T Consequently themagnets become excited and attract and draw rearwardly the armature Zfrom beneath the projection L, thus permitting the plate or chute M tofall-into alinement with the chute G to receive the coke there- 'fromand conduct it by gravity to a receptacle separate from that whichreceives the cin- 5 ductors of electricity are brought into conders. Ateach oscillation of the magnetframe the arm S replaces the chute M intoapproximated vertical though slightly-inclined position and if thecurrent be broken 5 releases the armature Z and leaves it in positionWhere it is retained by the Weight Z to support the projection L andchute M.

Having noW particularly described and aseertained the nature of my saidinvention and in What manner the same is to be constructed and operated,Ideclare that What I claim is 1. An apparatus for separating coke fromcinders and other substances, comprising a rotary drum having upon itssurface channels or receptacles for receiving the material to beseparated, a stationary chute for delivering material from said drum, amovable chute in proximity to said stationary chute, and automatic meansfor shifting said movable chute into position to deflect coke and 2 5tary drum having upon its surface channels or receptacles for receivingthe material to be separated, electrical conductors contiguous to saidchannels or receptacles, electromagnets electrically connected with saidconductors, a

3 stationary chute for delivering material from said drum, a movablechute in proximity to said stationary chute, and means operable by saidelectromagnets for automatically shifting said movable chute intoposition to deflect coke and other electrically-00nductive substancesfrom said stationary chute.

3. An apparatus for separating coke from cinders and other substances,comprising a rotary drum provided upon its surface with channels orreceptacles for receiving the material to be separated, electricalconductors contiguous to said channels or receptacles, electromagnetselectrically connected with said conductors, a stationary chute fordelivering material from said drum, a gravity-positioned chute pivotedin proximity to said stationary chute for deflecting coke and otherconductors of electricity from the same, and means operated by saidelectromagnets for automatically locking said gravity-positioned chutein inoperative position and for automatically unlocking the same.

In testimony that I claim the foregoing as my invention 1 have signed myname in presence of two subscribing witnesses.
